usb Controllers - how many should I have

Andy1 · October 30, 2002, 11:28pm

Hi all:

I am attempting to get a customers HP DEskjet 656C USB printer working,
using 6.2, devu-uhci starts and devu-prn also runs. Attempts at printing
just lock up. I think its blocking on the output to the printer.

While researching the customers setup, I noticed that different machines
have different numbers of USB Controllers ! One of the office desktops has
one controller, the customers machine has two and my IBM laptop has 3. I
have appended the output of the IBM’s pci -v . Note that the three
controllers have different device_id’s and port addresses. Of these three
machines the only one that has USB that works is the desktop (1 contoller).

Why do I see up to three controllers? Is this normal? Which one is the
correct one? and How do I start devu-ohci to select one or the other ?

Also the printer is USB 2.0 should this work with uhci 1.1 ?

TIA Andy.

Yes some machines have multiple USB controllers. Each controller would
normally be responsible for 2 USB ports

With the current USB drivers you need to start a USB ver driver for
each controller. To do this you need to use the ‘-p’ option and
the ‘-N’ option.

use devu-uhci

devu-uhci Driver for Universal Host Controller Interface (UHCI) USB controllers.

Syntax:
devu-uhci [options*] &

Options:
-n name Set stack name. default “/dev/usb”
-p index Start stack on the USB controller with a pci index of
“index”. default 0.
-v Be verbose.

So to start devu-uhci for more than 1 controller :

devu-uhci -n /dev/usb0 -p1
devu-uhci -n /dev/usb1 -p2

This also means that you may need to start multiple class drivers( devu-prn )
to attach to each of the the USB host drivers.

devu-prn -n /dev/usbprn0 -s /dev/usb0
devu-prn -n /dev/usbprn1 -s /dev/usb1

: Also the printer is USB 2.0 should this work with uhci 1.1 ?

: TIA Andy.

Henry:

Thats great information. Thank you.

I gave it a try and discovered that all three of my USB controllers are at
the same PCI index (0). However they do have different IO addresses, is
there a way to differentiate one controller from another by using the IO
address? If there is then it appears to be undocumented.

TIA Andy.

Yes some machines have multiple USB controllers. Each controller would
normally be responsible for 2 USB ports

With the current USB drivers you need to start a USB ver driver for
each controller. To do this you need to use the ‘-p’ option and
the ‘-N’ option.

use devu-uhci

devu-uhci Driver for Universal Host Controller Interface (UHCI) USB
controllers.

Syntax:
devu-uhci [options*] &

Options:
-n name Set stack name. default “/dev/usb”
-p index Start stack on the USB controller with a pci
index of
“index”. default 0.
-v Be verbose.

So to start devu-uhci for more than 1 controller :

devu-uhci -n /dev/usb0 -p1
devu-uhci -n /dev/usb1 -p2

This also means that you may need to start multiple class drivers(
devu-prn )
to attach to each of the the USB host drivers.

devu-prn -n /dev/usbprn0 -s /dev/usb0
devu-prn -n /dev/usbprn1 -s /dev/usb1

: Also the printer is USB 2.0 should this work with uhci 1.1 ?

: TIA Andy.

The ‘-p index’ option should do what you want. It tells the driver to attach
to the ‘index’ occurrence of a controller. Index should start at 0 not 1
as I eluded to in my example below.

That’s it… It works perfectly.

In my case the second controller is the one for the ‘real’ USB ports. I use
"usb-uhci -p1 ", then I can see the attached usb devices on /dev/usb.

Thanks for the info…

The ‘-p index’ option should do what you want. It tells the driver to
attach
to the ‘index’ occurrence of a controller. Index should start at 0 not 1
as I eluded to in my example below.
